Wave Optics Question 10

Question 10 - 31 January - Shift 2

Two light waves of wavelengths 800 and $600 nm$ are used in Young’s double slit experiment to obtain interference fringes on a screen placed $7 m$ away from plane of slits. If the two slits are separated by $0.35 mm$, then shortest distance from the central bright maximum to the point where the bright fringes of the two wavelength coincide will be $mm$
